How do I check my PC specs on Ubuntu 20.04.3 LTS?

Question

I do not know how to check the PC specs on Ubuntu. Is there a specific command for this? Or do I search it in the menu?

Tell me if I need to provide extra info.

Answer 1

Go to Settings → About. You get some info there.

Else commands like lshw give you a complete list.

Answer 2

You can also use neofetch. First install it:

sudo apt update
sudo apt install neofetch

To use it type

neofetch

and you will get something like this:

Answer 3

I usually use the commands cat /proc/cpuinfo (to get detailed information about the cpu including clock speeds etc.) and lspci (to get all devices connected to the pci buses such as graphics cards etc.), and of course these are specifically to get information regarding the CPU and pci devices. To get an idea of the installed memory, use the top command which shows the current usage of the system processor and memory along with the task id of each process using the resources.

Also, the htop and glances commands are really nice, but you might have to install them through apt-get.

Answer 4

This is the command I use which gives the System Info, System Configuration and System Boot Info which is the computer's DMI in a human readable format:

$ sudo dmidecode -t system

For example:

# dmidecode 3.3
Getting SMBIOS data from sysfs.
SMBIOS 2.8 present.
Handle 0x0001, DMI type 1, 27 bytes
